To @ZZ whom Yizm'cu/ Liemeer/m Be' it` known' that I, `Louis H'. Canin" citizen of the United States, yresinng at Minneapolis` in the county of Hennepin' and State of Minnesota, have' invented certainv new and useful In'iprovements in Ste1icils`,of` which the' following is a specification, ,refs

erence beingha'd'to the accompanying drawings.

tion to provide a device of this general character having novel land improved means whereby the same maybe properly positioned upon the work.

Another object of the invention is to provide a novel and improved `device of this general character whereby varying areas may be properly treated with a sand-blast together withl means whereby a sand-blast may be employed for producing a suitable symbol upon the glass.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved stencil whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

as will be hereinafter more fully set forth.y

The novel features of my invention will hereinafter be definitelv claimed.

In order that myvinvention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in top plan illustrating a stencil constructed in accordance with an embodiment of my inventionand in applied position, the same being` assembled for use for the production of a symbol.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1;

Figure f3 is a sectional view taken substantially on the line 3 3 of Figure l;

Figure 4 is a sectional view tal/:en through the device with the removable rings omitted;

Figure 5 is a sectional view taken through a removable ring adapted foruse in connection with the structure illustrated in Figure 4.

As disclosed in the accompanying drawis, a"

ings, 1 denotes an annular member of suitable` material, preferably rubber, providing' a centra-l opening 2 of a relatively large diameter." The member 1l is broad and has' its opposed faces flat whereby the same may be." readily appliedto thesurface'of a plate P. i i Cemented or otherwise secured Lto the mnermarginal portion of the member 1 is an'annular member' 3 preferably of metal, the inner marginal portion of said member 3 overlying the lcentral opening 2 of the member 1.`

VAn annular member 4 is adapted to be snugly fitted within the opening 2 of the member 1, said member 4 being of substantially the same thickness as the member 1. With the member`4 in applied position the member 3 serves to maintain the member 4 in proper position upon the plate P. When it is desired to cut a hole through the platey l?, a member 4 is operatively engaged .with the member 1 having a central opening 5 of a diameter in accordance with the size of the opening desired to be produced in the plate P. i

After the assembled members 1. and 4 have been properly positioned upon the plate P the same are held in such position through the instrumentality of suitable clamps 6, said clamps preferably having direct contact with the member 3.

It is to be understood that my improved stencil is adapted for use in connection with a sand-blast in a manner commonly employed in the cutting of glass and when so used the close contact of the members 1 and 4 with the plate P assures the proper cutting action of the blast upon the glass.

When it is desired to produce a symbol upon the surface of the glass, the required member 4 is applied to the member 1 and within the central opening 5 of suoli applied member 4 is suitably arranged the supplemental stencil S cut in accordance with the design desired, the opposed portions of said stencil S and the member 4 having coacting therewith the bridge pieces 7 for maintaining the supplemental stencil S in desired position.

The stencil S is also preferably formed of rubber and when it is required to initially produce said stencil in separable parts in order to produce the. desired lines, the adjacent parts of such stencil are also connected by a suitable bridge piece, as indicated at 8.

From the foregoing description -it is thought to be obvious that a stencil constructed m accordance with my invention 1s particularly Well adapted for `use by reason of the convenience and facility With which it may be assembled and operated, and it will also be obvious that my invention issusceptible of some change and modification wit-hout departing from the principles and spirit thereof and for this reason I do not wish to bc understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

1. A device of the class described comprising a strip of material defining an opening, a member carried by the strip and partially overlying the central opening defined =by the strip, and a sepa able member defining an opening, said member being snugly insertible Within the opening defined by the strip, the strip and second member being of yieldable material and coplanar when in assembled relation.

2. A device of the class described comprising a strip of material defining'an opening, a member carried by the strip and partially overlying the central opening defined by the strip, a separable member defining an opening, said member being snugly insertible Within the opening defined by the strip, said strip and separable member being coplanar When in assembled relation, and a stencil adapted t0 be positioned Within the opening defined by the first named membeigsaid stencil being of yieldable material.

In testimony whereof I hereunto affix my signature. f
